2 Claims.

5 vide means whereby a press originally designed for printing paperhaving a specified number of columns may be readily changed for theprinting of a paper of a different number of columns without resortingto the necessity of providing a new ink rail.

A further object of the invention is to provide means associated withthe ink rail of printing mechanism whereby the inking mechanism may bemade to conform to printing or impression mechanism of different widthsor involving varied numbers of printed columns, which means may bereadily applied to or removed from the inking rail without disturbing orresorting to any material change or alteration of the ink supplymechanism thereof.

With these objects in view, together with others which will appear asthe description proceeds, the invention consists in the novelconstruction, combination and arrangement of parts all as will bedescribed more fully hereinafter, illustrat ed in the drawing andparticularly pointed out in the claims:-

In the drawing: 7

Fig 1 is a fragmentary diagrammatic side elevation of a portion of aconventional newspaper printing machine and showing the application ofthe invention thereto,

Fig. 2 is an enlarged fragmentary sectional view taken through the inkrail constructed in accordance with the invention, and

Fig. 3 .is a fragmentary plan view of the ink rail.

Referring now to the drawing, and particularly to Fig. 1 thereof, theconventional newspaper printing machine includes an impression cylindercylinder D, ink distributing rollers E, a first ink cylinder F, an inkpump G and an ink rail H. While the construction illustrated discloses afamiliar type of newspaper printing machine, it will be understood thatthe specific arrangement of the roll train isnot essential to properoperation of the invention, as the invention may be carried outsuccessfully in connection with other types of printing machines.

It will be understood that the ink rail H extends substantially the fullwidth of the ink cylinder F, and carries tubes or ducts Ito deliver inkfrom the pump G to the throat J. These tubes correspond in number to thecolumns which the press is designed to print. In instances where it isdesired to vary the numberof columns to be printed or to change thewidththereof, it has heretofore been necessary to supplya new ink railto correspond'to the changed widths or numbers of columns of theimpression cylinder. As has been heretofore stated, it is the primarypurpose of the present invention to dispense with the substitution of anentire new ink rail when conditions such as those mentioned occur.

In carrying out the invention the throat bar J is made separate from theink rail, and bolts or other securing members K are used in securing thethroat bar to the rail. This throat bar, it will be understood, isequipped with ink delivery ports L of a width corresponding to thecolumn width of the paper to be printed, and ink is supplied to theseports by tubes M carried by the throat and detachably connected as bymeans of unions N to the supply tubes I of the ink rail.

From this construction, it is apparent that when it is desired to changethe size or column arrangement of the newspaper, it is but necessary todetach the throat bar J and to substitute therefor a new barcorresponding to the rearranged column design. This change may bereadily and expeditiously made without the neces-, sity of special skillor tools; the tubesM, of course, being connected in the manner describedto the ink supply tubes carried by the ink rail H.

Having thus described my invention, I claimz 1. .In a printing machine,the combination with an ink cylinder, of an ink rail, ink conveyingtubes nested in and supported by the ink rail, a throat bar detachablysecured to the ink rail and having an arcuate surface conforming to andcooperating with the periphery of the ink cylinder, means supported bythe throat bar for conveying ink to its arcuate surface and theperiphery of the ink cylinder, said means being detachably A, a formcylinder B, form rollers C, a second 1nk secured to'the tubes.

2. In a printing machine, the combination with an ink cylinder, of anink rail, ink conveying tubes supported by the ink rail, a throat bardetachably secured to the ink rail and having an arcuate surfaceconforming to and cooperating with the periphery of the ink cylinder,tubes extending through the throat bar for conveying ink to the arcuatesurface of the throat bar and the periphery of the ink cylinder, andmeans for detachably securing the tubes of the throat bar to V
